Objective: A systematic review was carried out to determine the evidence for teaching pursed lips breathing (PLB) to patients with stable chronic obstructive pulmonary disease (COPD). Exertional dyspnoea is the single most important factor limiting function for people with COPD and PLB is commonly advocated for its management. Method: A literature search of Medline, PEDro and CINAHL Plus was conducted. Articles were included if they studied the effects of PLB in stable COPD and excluded when proxy interventions or significant modifications of PLB were used. Where comparable data were available they were pooled using weighted means. Results: Eleven studies involving 226 participants were included; four of the studies were of moderate quality according to the grading of recommendations assessments, development and evaluation (GRADE) system; the remaining studies were of low quality. Although no high quality evidence was identified, the direction of effect for PLB was consistently towards benefit, with the exception of one low quality study. Moderate quality evidence demonstrates that in stable COPD pursed lips breathing increases oxygen saturation and tidal volume, reduces respiratory rate at rest and reduces time taken to recover to pre-exercise breathlessness levels. One RCT showed reduction in exertional dyspnoea and improvement in functional performance at 3 months. Additionally, the evidence suggests that not all patients with COPD respond equally to PLB: those with moderate to severe COPD are most likely to benefit. Conclusion: High quality studies are required to identify PLB responders from non-responders and to determine whether short-term effects translate into clinically significant benefit.

Aims: To establish the causes and circumstances of all deaths occurring at work or related to work among fishermen in British commercial fishing between 1976 and 1995. Methods: A retrospective study, based on official mortality files, with a population of 440 355 fishermen-years at risk. Results: Of 616 deaths in British fishing, 454 (74%) were due to accidents at work, and 394 (87%) of these fishermen drowned. A total of 270 accidents were caused by casualties to vessels and 184 by personal accidents. There was no significant decline in the fatal accident rate, 103.1 per 100 000 fishermen-years, between 1976 and 1995. The fatal accident rate was 52.4 times higher (95% CI 42.9 to 63.8) than for all workers in Great Britain during the same period, and this relative risk increased through the 1980s up to 76.6 during 1991-95. Relative risks with the construction (12.3) and manufacturing (46.0) industries were higher than 5 and 20 respectively, during 1959-68. Trawlers foundering in adverse weather was the most frequent cause of mortality from casualties to vessels (115 deaths), and 82 of 145 personal accidents at sea arose during operations involving trawling nets. Conclusions: When compared with shore based industries, fishing remains at least as hazardous as before. Prevention should be aimed, most importantly, at the unnecessary operation of small vessels and trawling net manoeuvres in hazardous weather and sea conditions. Other measures should focus on preventing falls overboard, reducing fatigue, a more widespread use of personal flotation devices, and improvements in weather forecast evaluation.

BACKGROUND: Data on long-term trends in mortality are generally unavailable for multiple-cause coding of deaths. We wanted to know whether multiple-cause coding of deaths for myocardial infarction contributes much to the interpretation of death certificate data on mortality rates for this condition. METHODS: We analysed all causes of death on death certificates in the former Oxford health service region from 1979 to 1998. RESULTS: Of 69,333 death certificates that included myocardial infarction as a cause of death, it was the underlying cause of death in 93.6 per cent. The ratio of 'mentions' to 'underlying cause' was broadly similar over the study period, during which time there were substantial falls in mortality rates. There were significant changes to the ratios, associated with timing of changes to coding rules; but their effects were small. The ratio of mentions to underlying cause was similar in men and women and in different age groups. CONCLUSION: The underlying cause of death was a robust and almost complete measure of certified deaths for myocardial infarction. [ABSTRACT FROM AUTHOR]

The aim of this study was to investigate the most hazardous of all occupations in Great Britain. The causes of all deaths in British merchant seafaring and trawler fishing, traditionally the two most dangerous occupations, were established for the period between 1976 and 1995 and compared with official mortality statistics for other occupations. Fishermen were 52.4 times more likely to have a fatal accident at work (95% CI 42.9-63.8), and seafarers were 26.2 times more likely (19.8-34.7), compared with other British workers. Although the number of work-related deaths has decreased in recent decades, in relative terms the occupations of fishing and seafaring remain as hazardous as before. If mortality rates in these occupations are to decrease, unsafe working practices, especially unnecessary operations in treacherous conditions, should be reduced. [ABSTRACT FROM AUTHOR]

Abstract Background A strong consensus exists for a systematic approach to linguistic validation of patient reported outcome measures (PROMs) and discrete methods for assessing their psychometric properties. Despite the need for robust evidence of the appropriateness of measures, transition from linguistic to psychometric validation is poorly documented or evidenced. This paper demonstrates the importance of linking linguistic and psychometric testing through a purposeful stage which bridges the gap between translation and large-scale validation. Findings Evidence is drawn from a study to develop a Welsh language version of the Beck Depression Inventory-II (BDI-II) and investigate its psychometric properties. The BDI-II was translated into Welsh then administered to Welsh-speaking university students (n = 115) and patients with depression (n = 37) concurrent with the English BDI-II, and alongside other established depression and quality of life measures. A Welsh version of the BDI-II was produced that, on administration, showed conceptual equivalence with the original measure; high internal consistency reliability (Cronbach’s alpha = 0.90; 0.96); item homogeneity; adequate correlation with the English BDI-II (r = 0.96; 0.94) and additional measures; and a two-factor structure with one overriding dimension. Nevertheless, in the student sample, the Welsh version showed a significantly lower overall mean than the English (p = 0.002); and significant differences in six mean item scores. This prompted a review and refinement of the translated measure. Conclusions Exploring potential sources of bias in translated measures represents a critical step in the translation-validation process, which until now has been largely underutilised. This paper offers important findings that inform advanced methods of cross-cultural validation of PROMs.

Abstract This correction reports changes in our protocol since its publication. These include changes to authorship and acknowledgements, together with improvements to study design and procedures, and correction of an internal inconsistency. The improvements relate to the exclusion criteria, assessments carried out at screening, and mode of data collection.

Abstract Background Clinical depression is common, debilitating and treatable; one in four people experience it during their lives. The majority of sufferers are treated in primary care and only half respond well to active treatment. Evidence suggests that folate may be a useful adjunct to antidepressant treatment: 1) patients with depression often have a functional folate deficiency; 2) the severity of such deficiency, indicated by elevated homocysteine, correlates with depression severity, 3) low folate is associated with poor antidepressant response, and 4) folate is required for the synthesis of neurotransmitters implicated in the pathogenesis and treatment of depression. Methods/Design The primary objective of this trial is to estimate the effect of folate augmentation in new or continuing treatment of depressive disorder in primary and secondary care. Secondary objectives are to evaluate the cost-effectiveness of folate augmentation of antidepressant treatment, investigate how the response to antidepressant treatment depends on genetic polymorphisms relevant to folate metabolism and antidepressant response, and explore whether baseline folate status can predict response to antidepressant treatment. Seven hundred and thirty patients will be recruited from North East Wales, North West Wales and Swansea. Patients with moderate to severe depression will be referred to the trial by their GP or Psychiatrist. If patients consent they will be assessed for eligibility and baseline measures will be undertaken. Blood samples will be taken to exclude patients with folate and B12 deficiency. Some of the blood taken will be used to measure homocysteine levels and for genetic analysis (with additional consent). Eligible participants will be randomised to receive 5 mg of folic acid or placebo. Patients with B12 deficiency or folate deficiency will be given appropriate treatment and will be monitored in the 'comprehensive cohort study'. Assessments will be at screening, randomisation and 3 subsequent follow-ups. Discussion If folic acid is shown to improve the efficacy of antidepressants, then it will provide a safe, simple and cheap way of improving the treatment of depression in primary and secondary care.

Abstract Background Most of the randomized placebo-controlled trials that have examined the clinical effects of multivitamin-mineral supplements on infection in the elderly have shown no significant effect. The exceptions are three such trials, all using a supplement with the same composition, and all claiming dramatic benefits: a frequently cited study published in 1992, which reported a 50% reduction in the number of days of infection (NDI), and two 2002 replication studies. Questions have been raised about the 1992 report; a second report in 2001 based on the same trial, but describing effects of the supplement on cognitive functions, has been retracted by Nutrition. The primary purpose of the present paper is to evaluate the claims about the effects of supplements on NDI in the two replication reports. Methods Examination of internal consistency (outcomes of statistical tests versus reported data); comparison of variability of NDI across individuals in these two reports with variability in other trials; estimation of the probability of achieving the reported close agreement with the original finding. Results The standard deviations of NDI and levels of statistical significance reported are profoundly inconsistent. The reported standard deviations of NDI are consistently below what other studies have found. The reported percent reductions in NDI agree too closely with the original study. Conclusion The claims of reduced NDI in the two replication reports should be questioned, which also adds to concerns about the 1992 study. It follows that there is currently no trustworthy evidence from randomized placebo-controlled clinical trials that favors the use of vitamin-mineral supplements to reduce infection in the elderly.

Objective: The aim of this study was to develop and validate an instrument to measure Belonging in Surgery among surgical residents., Background: Belonging is the essential human need to maintain meaningful relationships and connections to one's community. Increased belongingness is associated with better well-being, job performance, and motivation to learn. However, no tools exist to measure belonging among surgical trainees., Methods: A panel of experts adapted a belonging instrument for use among United States surgery residents. After administration of the 28-item instrument to residents at a single institution, a Cronbach alpha was calculated to measure internal consistency, and exploratory principal component analyses were performed. Multiple iterations of analyses with successively smaller item samples suggested the instrument could be shortened. The expert panel was reconvened to shorten the instrument. Descriptive statistics measured demographic factors associated with Belonging in Surgery., Results: The overall response rate was 52% (114 responses). The Cronbach alpha among the 28 items was 0.94 (95% CI: 0.93-0.96). The exploratory principal component analyses and subsequent Promax rotation yielded 1 dominant component with an eigenvalue of 12.84 (70% of the variance). The expert panel narrowed the final instrument to 11 items with an overall Cronbach alpha of 0.90 (95% CI: 0.86, 0.92). Belonging in Surgery was significantly associated with race (Black and Asian residents scoring lower than White residents), graduating with one's original intern cohort (residents who graduated with their original class scoring higher than those that did not), and inversely correlated with resident stress level., Conclusions: An instrument to measure Belonging in Surgery was validated among surgical residents. With this instrument, Belonging in Surgery becomes a construct that may be used to investigate surgeon performance and well-being., Competing Interests: The authors report no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Monoclonal antibodies have revolutionized therapies, but non-immunoglobulin scaffolds are becoming compelling alternatives owing to their adaptability. Their ability to be labeled with imaging or cytotoxic compounds and to create multimeric proteins is an attractive strategy for therapeutics. Focusing on HER2, a frequently overexpressed receptor in breast cancer, this study addresses some limitations of conventional targeting moieties by harnessing the potential of these scaffolds. HER2-binding Affimers were isolated and characterized, demonstrating potency as binding reagents and efficient internalization by HER2-overexpressing cells. Affimers conjugated with cytotoxic agent achieved dose-dependent reductions in cell viability within HER2-overexpressing cell lines. Bispecific Affimers, targeting HER2 and virus-like particles, facilitated efficient internalization of virus-like particles carrying enhanced green fluorescent protein (eGFP)-encoding RNA, leading to protein expression. Anti-HER2 affibody or designed ankyrin repeat protein (DARPin) fusion constructs with the anti-VLP Affimer further underscore the adaptability of this approach. This study demonstrates the versatility of scaffolds for precise delivery of cargos into cells, advancing biotechnology and therapeutic research., Competing Interests: The authors declare a potential conflict of interest.

Mucinous cystic neoplasms (MCNs) are rare tumors primarily observed in the pancreas but occasionally found in other locations such as the retroperitoneum, ovary, liver, and spleen. These neoplasms are histologically classified based on the degree of dysplasia, with some associated with invasive carcinoma. Colorectal surgeons infrequently encounter MCNs. Mesenteric MCNs pose a diagnostic challenge secondary to their atypical location, subtle histology, and lack of specific biochemical markers. In this context, we present a case involving a 68-year-old female who initially presented with an assumed ovarian mass. Subsequent exploration revealed a 12 cm MCN situated in the sigmoid mesentery, a location seldom associated with these tumors. The patient underwent laparotomy with successful resection and recovery. Histopathological analysis confirmed the neoplasm's mucinous epithelium with a complex papillary architecture. Immunohistochemical staining supported the diagnosis, revealing positivity for CK7, SATB2, and CDX2., Competing Interests: The authors have declared financial relationships, which are detailed in the next section., (Copyright © 2024, Amy et al.)

Clinical guidelines include monitoring blood test abnormalities to identify patients at increased risk of undiagnosed cancer. Noting blood test changes over time may improve cancer risk stratification by considering a patient's individual baseline and important changes within the normal range. We aimed to review the published literature to understand the association between blood test trends and undiagnosed cancer. MEDLINE and EMBASE were searched until 15 May 2023 for studies assessing the association between blood test trends and undiagnosed cancer. We used descriptive summaries and narratively synthesised studies. We included 29 articles. Common blood tests were haemoglobin (24%, n = 7), C-reactive protein (17%, n = 5), and fasting blood glucose (17%, n = 5), and common cancers were pancreatic (29%, n = 8) and colorectal (17%, n = 5). Of the 30 blood tests studied, an increasing trend in eight (27%) was associated with eight cancer types, and a decreasing trend in 17 (57%) with 10 cancer types. No association was reported between trends in 11 (37%) tests and breast, bile duct, glioma, haematological combined, liver, prostate, or thyroid cancers. Our review highlights trends in blood tests that could facilitate the identification of individuals at increased risk of undiagnosed cancer. For most possible combinations of tests and cancers, there was limited or no evidence.

Objective: To determine the association between post-discharge mental healthcare and odds of readmission after emergency general surgery (EGS) hospitalization for patients with serious mental illness (SMI)., Background Data: A mental health visit (MHV) after medical hospitalization is associated with decreased readmissions for patients with SMI. The impact of a MHV after surgical hospitalization is unknown., Methods: Using Medicare claims, we performed a retrospective cohort study of hospitalized EGS patients with SMI aged >65.5 (2016-2018). EGS included colorectal, general abdominal, hepatopancreatobiliary, hernia, intestinal obstruction, resuscitation, and upper gastrointestinal conditions. SMI was defined as schizophrenia spectrum, mood, or anxiety disorders. The exposure was MHV within 30 days of discharge. The primary outcome was 30-day readmission. Secondary outcomes included emergency department presentation and psychiatric admission. Inverse probability weighting was used to evaluated outcomes., Results: Of 88,092 analyzed patients, 11,755 (13.3%) had a MHV within 30 days of discharge. 23,696 (26.9%) of patients were managed operatively, 64,395 (73.1%) non-operatively. After adjustment for potential confounders, patients with a post-discharge MHV had lower odds of acute care readmission than patients without a MHV in both operative (OR 0.60; 95% CI: [0.40-0.90]) and non-operative (OR 0.67; 95% CI [0.53-0.84]) cohorts. There was no association between post-discharge MHV and ED presentation or psychiatric admission in the operative or non-operative groups., Conclusions: Post-discharge MHV after EGS hospitalization was associated with decreased odds of readmission for patients with SMI managed operatively and nonoperatively. In older EGS patients with SMI, coordination of MHVs may be a mechanism to reduce readmission disparities., Competing Interests: Conflict of Interest: None., (Copyright © 2024 Wolters Kluwer Health, Inc.

Objective: Many emergency general surgery (EGS) conditions can be managed operatively or nonoperatively, with outcomes that vary by diagnosis. We hypothesized that operative management would lead to higher in-hospital costs but to cost savings over time., Background: EGS conditions account for $28 billion in health care costs in the United States annually. Compared with scheduled surgery, patients who undergo emergency surgery are at increased risk of complications, readmissions, and death, with accompanying costs of care that are up to 50% higher than elective surgery. Our prior work demonstrated that operative management had variable impacts on clinical outcomes depending on the EGS condition., Methods: This was a nationwide, retrospective study using fee-for-service Medicare claims data. We included patients 65.5 years of age or older with a principal diagnosis for an EGS condition 7/1/2015-6/30/2018. EGS conditions were categorized as: colorectal, general abdominal, hepatopancreaticobiliary (HPB), intestinal obstruction, and upper gastrointestinal. We used near-far matching with a preference-based instrumental variable to adjust for confounding and selection bias. Outcomes included Medicare payments for the index hospitalization and at 30, 90, and 180 days., Results: Of 507,677 patients, 30.6% received an operation. For HPB conditions, costs for operative management were initially higher but became equivalent at 90 and 180 days. For all others, operative management was associated with higher inpatient costs, which persisted, though narrowed, over time. Out-of-pocket costs were nearly equivalent for operative and nonoperative management., Conclusions: Compared with nonoperative management, costs were higher or equivalent for operative management of EGS conditions through 180 days, which could impact decision-making for clinicians, patients, and health systems in situations where clinical outcomes are similar., Competing Interests: The authors report no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Introduction: The main objective was to compare suicide rates and their trends across the three UK Armed forces (Royal Navy, Army and Royal Air Force) from 1900 to 2020. Further objectives were to compare suicide rates with those in the corresponding general population and in UK merchant shipping and to discuss preventative measures., Methods: Examination of annual mortality reports and returns, death inquiry files and official statistics. The main outcome measure was the suicide rate per 100 000 population employed., Results: Since 1990, there have been significant reductions in suicide rates in each of the Armed Forces, although a non-significant increase in the Army since 2010. Compared with the corresponding general population, during the most recent decade from 2010 up to 2020, suicide rates were 73% lower in the Royal Air Force, 56% lower in the Royal Navy and 43% lower in the Army. Suicide rates have been significantly decreased in the Royal Air Force since the 1950s, in the Royal Navy since the 1970s and in the Army since the 1980s (comparisons for the Royal Navy and the Army were not available from the late 1940s to the 1960s).During the earliest decades from 1900 to the 1930s, suicide rates in the Armed Forces were mostly quite similar or moderately increased compared with the general population, but far lower than in merchant shipping. Following legislative changes in the last 30 years, suicide rates through poisoning by gases and through firearms or explosives have fallen sharply., Conclusions: The study shows that suicide rates in the Armed Forces have been lower than in the general population over many decades. The sharp reductions in suicide rates over the last 30 years suggest the effectiveness of recent preventative measures, including reductions in access to a method of suicide and well-being initiatives., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Furries can be described as a mediacentric fandom, similar to other fandoms, which organizes around an interest in anthropomorphic art. Past research has also aimed to highlight and understand the sexual motivations of furries, leading to questions regarding the relative strength of fandom and sexual motivations for joining and maintaining membership within the group. The goal of the present study was to test the relative contributions sex- and fandom-related motivations (e.g., social belonging) have in determining furry identity to provide better conceptualizations of this unique community for future research and education. In a sample of furries ( n = 1,113), participants reported sexual attraction to facets of their interest and were found to be sexually motivated to engage in specific fan behaviors. However, a series of follow-up analyses revealed that non-sexual motivations were not only stronger in magnitude than sexual motivation was, but were also much more strongly correlated with furry identification.

Background: Several studies have reported large increases in the incidence of eosinophilic oesophagitis (EoE) in the last 20 years. We aimed to systematically review the incidence and prevalence of EoE, focused on all European countries., Methods: Systematic review and meta-analysis up to 31 December 2022, based on PubMed, CINAHL and extensive hand searching of reference lists. Twenty-five eligible studies were identified and included., Results: For both adults and children, the highest EoE incidence and prevalence have been reported from regional studies in Spain. EoE incidence for both adults and children was significantly lower (p < 0.001) in nationwide studies (meta-analysis = 3.64 per 100,000 person-years overall) compared with regional or centre-based studies (7.16). EoE incidence and prevalence were significantly higher (p < 0.001) in adults than children. All studies that reported on longitudinal trends in EoE incidence showed increases over time, more markedly during more recent years. Larger increases in incidence tend to refer to regional rather than nationwide studies; from Spain, Switzerland and Denmark, both for paediatric and adult age groups. Increases in EoE incidence 100,000 person-years were larger than for incidence per number of diagnostic endoscopies. The most frequently reported co-morbidities in adults were rhinitis, followed by asthma, food allergy and gastroesophageal reflux disease, and in children, erosive oesophagitis, asthma, food allergy and rhinitis., Conclusions: The incidence of EoE has increased in Europe over the last 30 years, exceeding increases in the volume of oesophago-gastro-duodenoscopies performed. The patchy and low incidence and prevalence of EoE generally in Europe and compared with North America, may reflect a lack of clinical awareness and research focus rather than a genuinely low incidence of EoE. A co-ordinated Europe-wide study that uses standardised methodology is urgently needed to provide a comprehensive picture of EoE incidence and prevalence across Europe., (© 2023 The Authors.

Importance: The benefit of primary care physician (PCP) follow-up as a potential means to reduce readmissions in hospitalized patients has been found in other medical conditions and among patients receiving high-risk surgery. However, little is known about the implications of PCP follow-up for patients with an emergency general surgery (EGS) condition., Objective: To evaluate the association between PCP follow-up and 30-day readmission rates after hospital discharge for an EGS condition., Design, Setting, and Participants: This cohort study used data from the Centers for Medicare & Medicaid Services Master Beneficiary Summary File, Inpatient, Carrier (Part B), and Durable Medical Equipment files for beneficiaries aged 66 years or older who were hospitalized with an EGS condition that was managed operatively or nonoperatively between September 1, 2016, and November 30, 2018. Eligible patients were enrolled in Medicare fee-for-service, admitted through the emergency department with a primary diagnosis of an EGS condition, and received a general surgery consultation during the admission. Data were analyzed between July 11, 2022, and June 5, 2023., Exposure: Follow-up with a PCP within 30 days after hospital discharge for the index admission., Main Outcomes and Measures: The primary outcome was readmission within 30 days after discharge for the index admission. An inverse probability weighted regression model was used to estimate the risk-adjusted association of PCP follow-up with 30-day readmission. The secondary outcome was readmission within 30 days after discharge stratified by treatment type (operative vs nonoperative treatment) during their index admission., Results: The study included 345 360 Medicare beneficiaries (mean [SD] age, 74.4 [12.0] years; 187 804 females [54.4%]) hospitalized with an EGS condition. Of these, 156 820 patients (45.4%) had a follow-up PCP visit, 108 544 (31.4%) received operative treatment during their index admission, and 236 816 (68.6%) received nonoperative treatment. Overall, 58 253 of 332 874 patients (17.5%) were readmitted within 30 days after discharge for the index admission. After risk adjustment and propensity weighting, patients who had PCP follow-up had 67% lower odds of readmission (adjusted odds ratio [AOR], 0.33; 95% CI, 0.31-0.36) compared with patients without PCP follow-up. After stratifying by treatment type, patients who were treated operatively during their index admission and had subsequent PCP follow-up within 30 days after discharge had 79% reduced odds of readmission (AOR, 0.21; 95% CI, 0.18-0.25); a similar association was seen among patients who were treated nonoperatively (AOR, 0.36; 95% CI, 0.34-0.39). Infectious conditions, heart failure, acute kidney failure, and chronic kidney disease were among the most frequent diagnoses prompting readmission overall and among operative and nonoperative treatment groups., Conclusions and Relevance: In this cohort study, follow-up with a PCP within 30 days after discharge for an EGS condition was associated with a significant reduction in the adjusted odds of 30-day readmission. This association was similar for patients who received operative care or nonoperative care during their index admission. In patients aged 66 years or older with an EGS condition, primary care coordination after discharge may be an important tool to reduce readmissions.

Introduction: Analyzing hospital-free days (HFDs) offers a patient-centered approach to health services research. We hypothesized that, within emergency general surgery (EGS), multimorbidity would be associated with fewer HFDs, whether patients were managed operatively or nonoperatively., Methods: EGS patients were identified using national Medicare claims data (2015-2018). Patients were classified as multimorbid based on the presence of a Qualifying Comorbidity Set and stratified by treatment: operative (received surgery within 48 h of index admission) and nonoperative. HFDs were calculated through 180 d, beginning on the day of index admission, as days alive and spent outside of a hospital, an Emergency Department, or a long-term acute care facility. Univariate comparisons were performed using Kruskal-Wallis tests and risk-adjusted HFDs were compared between multimorbid and nonmultimorbid patients using multivariable zero-inflated negative binomial regression models., Results: Among 174,891 operative patients, 45.5% were multimorbid. Among 398,756 nonoperative patients, 59.2% were multimorbid. Multimorbid patients had fewer median HFDs than nonmultimorbid patients among operative and nonoperative cohorts (P < 0.001). At 6 mo, among operative patients, multimorbid patients had 6.5 fewer HFDs (P < 0.001), and among nonoperative patients, multimorbid patients had 7.9 fewer HFDs (P < 0.001). When length of stay was included as a covariate, nonoperative multimorbid patients still had 7.9 fewer HFDs than nonoperative, nonmultimorbid patients (P < 0.001)., Conclusions: HFDs offer a patient-centered, composite outcome for claims-based analyses. For EGS patients, multimorbidity was associated with less time alive and out of the hospital, especially when patients were managed nonoperatively., (Copyright © 2023 Elsevier Inc.

Objective: To understand how multimorbidity impacts operative versus nonoperative management of emergency general surgery (EGS) conditions., Background: EGS is a heterogenous field, encompassing operative and nonoperative treatment options. Decision-making is particularly complex for older patients with multimorbidity., Methods: Using an instrumental variable approach with near-far matching, this national, retrospective observational cohort study of Medicare beneficiaries examines the conditional effects of multimorbidity, defined using qualifying comorbidity sets, on operative versus nonoperative management of EGS conditions., Results: Of 507,667 patients with EGS conditions, 155,493 (30.6%) received an operation. Overall, 278,836 (54.9%) were multimorbid. After adjustment, multimorbidity significantly increased the risk of in-hospital mortality associated with operative management for general abdominal patients (+9.8%; P = 0.002) and upper gastrointestinal patients (+19.9%, P < 0.001) and the risk of 30-day mortality (+27.7%, P < 0.001) and nonroutine discharge (+21.8%, P = 0.007) associated with operative management for upper gastrointestinal patients. Regardless of multimorbidity status, operative management was associated with a higher risk of in-hospital mortality among colorectal patients (multimorbid: + 12%, P < 0.001; nonmultimorbid: +4%, P = 0.003), higher risk of nonroutine discharge among colorectal (multimorbid: +42.3%, P < 0.001; nonmultimorbid: +55.1%, P < 0.001) and intestinal obstruction patients (multimorbid: +14.6%, P = 0.001; nonmultimorbid: +14.8%, P = 0.001), and lower risk of nonroutine discharge (multimorbid: -11.5%, P < 0.001; nonmultimorbid: -11.9%, P < 0.001) and 30-day readmissions (multimorbid: -8.2%, P = 0.002; nonmultimorbid: -9.7%, P < 0.001) among hepatobiliary patients., Conclusions: The effects of multimorbidity on operative versus nonoperative management varied by EGS condition category. Physicians and patients should have honest conversations about the expected risks and benefits of treatment options, and future investigations should aim to understand the optimal management of multimorbid EGS patients., Competing Interests: The authors report no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Importance: Sixty-five million individuals in the US live in primary care shortage areas with nearly one-third of Medicare patients in need of a primary care health care professional. Periodic health examinations and preventive care visits have demonstrated a benefit for surgical patients; however, the impact of primary care health care professional shortages on adverse outcomes from surgery is largely unknown., Objective: To determine if preoperative primary care utilization is associated with postoperative mortality following an emergency general surgery (EGS) operation among Black and White older adults., Design, Setting, and Participants: This was a retrospective cohort study that took place at US hospitals with an emergency department. Participants were Medicare patients aged 66 years or older who were admitted from the emergency department for an EGS condition between July 1, 2015, and June 30, 2018, and underwent an operation on hospital day 0, 1, or 2. The analysis was performed during December 2022. Patients were classified into 1 of 5 EGS condition categories based on principal diagnosis codes; colorectal, general abdominal, hepatopancreatobiliary, intestinal obstruction, or upper gastrointestinal. Mixed-effects multivariable logistic regression was used in the risk-adjusted models. An interaction term model was used to measure effect modification by race., Exposure: Primary care utilization in the year prior to presentation for an EGS operation., Main Outcome and Measures: In-hospital, 30-day, 60-day, 90-day, and 180-day mortality., Results: A total of 102 384 patients (mean age, 73.8 [SD, 11.5] years) were included in the study. Of those, 8559 were Black (8.4%) and 93 825 were White (91.6%). A total of 88 340 patients (86.3%) had seen a primary care physician in the year prior to their index hospitalization. After risk adjustment, patients with primary care exposure had 19% lower odds of in-hospital mortality than patients without primary care exposure (odds ratio [OR], 0.81; 95% CI, 0.72-0.92). At 30 days patients with primary care exposure had 27% lower odds of mortality (OR, 0.73; 95% CI, 0.67-0.80). This remained relatively stable at 60 days (OR, 0.75; 95% CI, 0.69-0.81), 90 days (OR, 0.74; 95% CI, 0.69-0.81), and 180 days (OR, 0.75; 95% CI, 0.70-0.81). None of the interactions between race and primary care physician exposure for mortality at any time interval were significantly different., Conclusions and Relevance: In this observational study of Black and White Medicare patients, primary care utilization had no impact on in-hospital mortality for Black patients, but was associated with decreased mortality for White patients. Primary care utilization was associated with decreased mortality for both Black and White patients at 30, 60, 90 and 180 days.

Introduction: Many emergency general surgery (EGS) conditions can be managed both operatively or nonoperatively; however, it is unknown whether the decision to operate affects Black and White patients differentially., Methods: We identified a nationwide cohort of Black and White Medicare beneficiaries, hospitalized for common EGS conditions from July 2015 to June 2018. Using near-far matching to adjust for measurable confounding and an instrumental variable analysis to control for selection bias associated with treatment assignment, we compare outcomes of operative and nonoperative management in a stratified population of Black and White patients. Outcomes included in-hospital mortality, 30-day mortality, nonroutine discharge, and 30-day readmissions. An interaction test based on a t test was used to determine the conditional effects of operative versus nonoperative management between Black and White patients., Results: A total of 556,087 patients met inclusion criteria, of which 59,519 (10.7%) were Black and 496,568 (89.3%) were White. Overall, 165,932 (29.8%) patients had an operation and 390,155 (70.2%) were managed nonoperatively. Significant outcome differences were seen between operative and nonoperative management for some conditions; however, no significant differences were seen for the conditional effect of race on outcomes., Conclusions: The decision to manage an EGS patient operatively versus nonoperatively has varying effects on surgical outcomes. These effects vary by EGS condition. There were no significant conditional effects of race on the outcomes of operative versus nonoperative management among universally insured older adults hospitalized with EGS conditions., Competing Interests: The authors declare no conflict of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Objective: Lack of insurance has been independently associated with an increased risk of in-hospital mortality after abdominal aortic aneurysm repair, possibly due to worse control of comorbidities and delays in diagnosis and treatment. Medicaid expansion has improved insurance rates and access to care, potentially benefiting these patients. We sought to assess the association between Medicaid expansion and outcomes after abdominal aortic aneurysm repair., Methods: A retrospective analysis of Healthcare Cost and Utilization Project State Inpatient Databases data from 14 states between 2012 and 2018 was conducted. The sample was restricted to first-record abdominal aortic aneurysm repairs in adults under age 65 in states that expanded Medicaid on January 1, 2014 (Medicaid expansion group) or had not expanded before December 31, 2018 (non-expansion group). The Medicaid expansion and non-expansion groups were compared between pre-expansion (2012-2013) and post-expansion (2014-2018) time periods to assess baseline demographic and operative differences. We used difference-in-differences multivariable logistic regression adjusted for patient factors, open vs endovascular repair, and standard errors clustered by state. Our primary outcome was in-hospital mortality. Outcomes were stratified by insurance type., Results: We examined 8995 patients undergoing abdominal aortic aneurysm repair, including 3789 (42.1%) in non-expansion states and 5206 (57.9%) in Medicaid expansion states. Rates of Medicaid insurance were unchanged in non-expansion states but increased in Medicaid expansion states post-expansion (non-expansion: 10.9% to 9.8%; P = .346; expansion: 9.7% to 19.7%; P < .001). One in 10 patients from both non-expansion and Medicaid expansion states presented with ruptured aneurysms, which did not change over time. Rates of open repair decreased in both non-expansion and Medicaid expansion states over time (non-expansion: 25.1% to 19.2%; P < .001; expansion: 25.2% to 18.4%; P < .001). On adjusted difference-in-differences analysis between expansion and non-expansion states pre-to post-expansion, Medicaid expansion was associated with a 1.02% absolute reduction in in-hospital mortality among all patients (95% confidence interval, -1.87% to -0.17%; P = .019). Additionally, among patients who were either on Medicaid or were uninsured (ie, the patients most likely to be impacted by Medicaid expansion), a larger 4.17% decrease in in-hospital mortality was observed (95% confidence interval, -6.47% to -1.87%; P < .001). In contrast, no significant difference-in-difference in mortality was observed for privately insured patients., Conclusions: Medicaid expansion was associated with decreased in-hospital mortality after abdominal aortic aneurysm repair among all patients and particularly among patients who were either on Medicaid or were uninsured. Our results provide support for improved access to care for patients undergoing abdominal aortic aneurysm repair through Medicaid expansion., (Copyright © 2023 Society for Vascular Surgery.

Research suggests that people at the interface of two different cultures may face a dilemma regarding how or whether to adopt aspects of the new culture in light of their existing cultural identity. A growing body of research in fan communities suggests that similar group processes may operate in recreational, volitional identities. We tested this by examining the associations between acculturation attitudes and identification with fan communities across three studies. Fanfiction fans, Star Wars fans, and furries completed measures of four different acculturation strategies with respect to managing their fan and non-fan communities as well as a measure of their identification with the fan community. Results across the three studies consistently found that integration and assimilation strategies positively predicted fan community identification, while separation and marginalization strategies negatively predicted fan community identification. Together, the results conceptually replicate and find evidence for the acculturation model.

Background: Communication is key to success in bariatric surgery. This study aims to understand how outcomes after bariatric surgery differ between patients with a non-English primary language and those with English as their primary language., Methods: This retrospective, observational cohort study of bariatric surgery patients age ≥ 18 years utilized the Michigan, Maryland, and New Jersey State Inpatient Databases and State Ambulatory Surgery and Services Databases, 2016 to 2018. Patients were classified by primary spoken language: English and non-English. Primary outcome was complications. Secondary outcomes included length of stay (LOS) and cost, with cost calculated using cost-to-charge ratios provided by Healthcare Cost and Utilization Project and reported in 2019 United States dollars. Multivariable regression models (logistic, Poisson, and quantile) were used to examine associations between primary language and outcomes. Given the uneven distribution of race by primary language, interaction terms were used to examine conditional effects of race., Results: Among 69,749 bariatric surgery patients, 2811 (4.2%) spoke a non-English primary language. Covariates, notably race distribution, and unadjusted outcomes differed significantly by primary language. However, after adjustment, non-English primary language was not associated with significantly increased odds of complications (odds ratio 1.24, p = 0.389), significantly different LOS (- 0.02 days, p = 0.677), nor significantly different mean healthcare costs (- $265, p = 0.309). There were no significant conditional effects of race seen among outcomes., Conclusions: Though non-English primary language was associated with a significantly different distribution of observable characteristics (including race, income quartile, and insurance type), after adjustment, non-English primary language was not associated with significant differential risk of adverse outcomes after bariatric surgery, and there were no significant conditional effects of race. As such, this study suggests that disparities in bariatric surgery by primary spoken language more likely related to access to care, or the pre- and post-hospital care continuum, rather than index hospitalization after surgery., (© 2023.

Background: Mental illness is associated with worse outcomes after emergency general surgery. To understand how preoperative processes of care may influence disparate outcomes, we examined rates of surgical consultation, treatment, and operative approach between older adults with and without serious mental illness (SMI)., Study Design: We performed a nationwide, retrospective cohort study of Medicare beneficiaries aged 65.5 years or more hospitalized via the emergency department for acute cholecystitis or biliary colic. SMI was defined as schizophrenia spectrum, mood, and/or anxiety disorders. The primary outcome was surgical consultation. Secondary outcomes included operative treatment and surgical approach (laparoscopic vs open). Multivariable logistic regression was used to examine outcomes with adjustment for potential confounders related to patient demographics, comorbidities, and rates of imaging., Results: Of 85,943 included older adults, 19,549 (22.7%) had SMI. Before adjustment, patients with SMI had lower rates of surgical consultation (78.6% vs 80.2%, p < 0.001) and operative treatment (68.2% vs 71.7%, p < 0.001), but no significant difference regarding laparoscopic approach (92.0% vs 92.1%, p = 0.805). In multivariable regression models with adjustment for confounders, there was no difference in odds of receiving a surgical consultation (odds ratio 0.98 [95% CI 0.93 to 1.03]) or undergoing operative treatment (odds ratio 0.98 [95% CI 0.93 to 1.03]) for patients with SMI compared with those without SMI., Conclusions: Older adults with SMI had similar odds of receiving surgical consultation and operative treatment as those without SMI. As such, differences in processes of care that result in SMI-related disparities likely occur before or after the point of surgical consultation in this universally insured patient population., (Copyright © 2023 by the American College of Surgeons.

Background: Multimorbidity is associated with an increased risk of poor surgical outcomes among older adults; however, identifying multimorbidity in the clinical setting can be a challenge., Objective: We created the Multimorbid Patient Identifier App (MMApp) to easily identify patients with multimorbidity identified by the presence of a Qualifying Comorbidity Set and tested its feasibility for use in future clinical research, validation, and eventually to guide clinical decision-making., Methods: We adapted the Qualifying Comorbidity Sets' claims-based definition of multimorbidity for clinical use through a modified Delphi approach and developed MMApp. A total of 10 residents input 5 hypothetical emergency general surgery patient scenarios, common among older adults, into the MMApp and examined MMApp test characteristics for a total of 50 trials. For MMApp, comorbidities selected for each scenario were recorded, along with the number of comorbidities correctly chosen, incorrectly chosen, and missed for each scenario. The sensitivity and specificity of identifying a patient as multimorbid using MMApp were calculated using composite data from all scenarios. To assess model feasibility, we compared the mean task completion by scenario to that of the American College of Surgeons National Surgical Quality Improvement Program Surgical Risk Calculator (ACS-NSQIP-SRC) using paired t tests. Usability and satisfaction with MMApp were assessed using an 18-item questionnaire administered immediately after completing all 5 scenarios., Results: There was no significant difference in the task completion time between the MMApp and the ACS-NSQIP-SRC for scenarios A (86.3 seconds vs 74.3 seconds, P=.85) or C (58.4 seconds vs 68.9 seconds,P=.064), MMapp took less time for scenarios B (76.1 seconds vs 87.4 seconds, P=.03) and E (20.7 seconds vs 73 seconds, P<.001), and more time for scenario D (78.8 seconds vs 58.5 seconds, P=.02). The MMApp identified multimorbidity with 96.7% (29/30) sensitivity and 95% (19/20) specificity. User feedback was positive regarding MMApp's usability, efficiency, and usefulness., Conclusions: The MMApp identified multimorbidity with high sensitivity and specificity and did not require significantly more time to complete than a commonly used web-based risk-stratification tool for most scenarios. Mean user times were well under 2 minutes. Feedback was overall positive from residents regarding the usability and usefulness of this app, even in the emergency general surgery setting. It would be feasible to use MMApp to identify patients with multimorbidity in the emergency general surgery setting for validation, research, and eventual clinical use. This type of mobile app could serve as a template for other research teams to create a tool to easily screen participants for potential enrollment., (©Claire Barthlow Rosen, Sanford Eugene Roberts, Solomiya Syvyk, Caitlin Finn, Jason Tong, Christopher Wirtalla, Hunter Spinks, Rachel Rapaport Kelz.

Objective: To determine the effect of operative versus nonoperative management of emergency general surgery conditions on short-term and long-term outcomes., Background: Many emergency general surgery conditions can be managed either operatively or nonoperatively, but high-quality evidence to guide management decisions is scarce., Methods: We included 507,677 Medicare patients treated for an emergency general surgery condition between July 1, 2015, and June 30, 2018. Operative management was compared with nonoperative management using a preference-based instrumental variable analysis and near-far matching to minimize selection bias and unmeasured confounding. Outcomes were mortality, complications, and readmissions., Results: For hepatopancreaticobiliary conditions, operative management was associated with lower risk of mortality at 30 days [-2.6% (95% confidence interval: -4.0, -1.3)], 90 days [-4.7% (-6.50, -2.8)], and 180 days [-6.4% (-8.5, -4.2)]. Among 56,582 intestinal obstruction patients, operative management was associated with a higher risk of inpatient mortality [2.8% (0.7, 4.9)] but no significant difference thereafter. For upper gastrointestinal conditions, operative management was associated with a 9.7% higher risk of in-hospital mortality (6.4, 13.1), which increased over time. There was a 6.9% higher risk of inpatient mortality (3.6, 10.2) with operative management for colorectal conditions, which increased over time. For general abdominal conditions, operative management was associated with 12.2% increased risk of inpatient mortality (8.7, 15.8). This effect was attenuated at 30 days [8.5% (3.8, 13.2)] and nonsignificant thereafter., Conclusions: The effect of operative emergency general surgery management varied across conditions and over time. For colorectal and upper gastrointestinal conditions, outcomes are superior with nonoperative management, whereas surgery is favored for patients with hepatopancreaticobiliary conditions. For obstructions and general abdominal conditions, results were equivalent overall. These findings may support patients, clinicians, and families making these challenging decisions., Competing Interests: The authors report no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: Juvenile Idiopathic Arthritis (JIA) is the most prevalent chronic pediatric rheumatic disorder. In joints of JIA patients, aggressive phenotypic changes in fibroblast-like synoviocytes (FLS) of the synovial lining play a key role in inflammation. MicroRNAs are dysregulated in rheumatoid arthritis and JIA, including miR-27a-3p. However, it is not understood if miR-27a-3p, enriched in JIA synovial fluid (SF) and leukocytes, alters FLS function., Methods: Primary JIA FLS cells were transfected with a miR-27a-3p mimic or a negative control microRNA (miR-NC) and stimulated with pooled JIA SF or inflammatory cytokines. Viability and apoptosis were analyzed by flow cytometry. Proliferation was evaluated using a 3 H-thymidine incorporation assay. Cytokine production was assessed by qPCR and ELISA. Expression of TGF-β pathway genes was determined using a qPCR array., Results: MiR-27a-3p was constitutively expressed in FLS. Overexpression of miR-27a-3p caused increased interleukin-8 secretion in resting FLS, and interleukin-6 was elevated in SF-activated FLS compared to miR-NC. Furthermore, stimulation with pro-inflammatory cytokines augmented FLS proliferation in miR-27a-3p-transfected FLS relative to miR-NC. Expression of multiple TGF-β pathway genes was modulated by overexpression of miR-27a-3p., Conclusions: MiR-27a-3p significantly contributes to FLS proliferation and cytokine production, making it a potential candidate for epigenetic therapy that targets FLS in arthritis., (© 2023.

Background: Qualifying comorbidity sets (QCS) are tools used to identify multimorbid patients at increased surgical risk. It is unknown how the QCS framework for multimorbidity affects surgical risk in different racial groups., Methods: This retrospective cohort study included Medicare patients age ≥65.5 who underwent an emergency general surgery operation from 2015 to 2018. Our exposure was race and multimorbidity, included in our model as an interaction term. The primary outcome of the study was 30-day mortality. Secondary outcomes included routine discharge, 30-day readmission, length of stay, and complications., Results: In total, 163,148 patients who underwent and operation were included in this study. Of these, 13,852 (8.5%, p < 0.001) were Black, and 149,296 (91.5%, p < 0.001) were White. Black multimorbid patients had no significant differences in 30-day mortality, routine discharge or 30-day readmission when compared to White multimorbid patients after risk-adjustment. Black multimorbid patients had significantly lower odds of complications (OR 0.89, p = 0.014) compared to White multimorbid patients., Conclusions: Our study of universally insured patients highlights the critical role of pre-operative health status and its association with surgical outcomes., Competing Interests: Declaration of competing interest This manuscript is not under consideration for publication in any other journal and the authors have no financial conflicts in relation to the content of the manuscript.

Importance: Variation in outcomes across hospitals adversely affects surgical patients. The use of high-quality hospitals varies by population, which may contribute to surgical disparities., Objective: To simulate the implications of data-driven hospital selection for social welfare among patients who underwent colorectal cancer surgery., Design, Setting, and Participants: This economic evaluation used the hospital inpatient file from the Florida Agency for Health Care Administration. Surgical outcomes of patients who were treated between January 1, 2016, and December 31, 2018 (training cohort), were used to estimate hospital performance. Costs and benefits of care at alternative hospitals were assessed in patients who were treated between January 1, 2019, and December 31, 2019 (testing cohort). The cohorts comprised patients 18 years or older who underwent elective colorectal resection for benign or malignant neoplasms. Data were analyzed from March to October 2022., Exposures: Using hierarchical logistic regression, we estimated the implications of hospital selection for in-hospital mortality risk in patients in the training cohort. These estimates were applied to patients in the testing cohort using bayesian simulations to compare outcomes at each patient's highest-performing and chosen local hospitals. Analyses were stratified by race and ethnicity to evaluate the potential implications for equity., Main Outcomes and Measures: The primary outcome was the mean patient-level change in social welfare, a composite measure balancing the value of reduced mortality with associated costs of care at higher-performing hospitals., Results: A total of 21 098 patients (mean [SD] age, 67.3 [12.0] years; 10 782 males [51.1%]; 2232 Black [10.6%] and 18 866 White [89.4%] individuals) who were treated at 178 hospitals were included. A higher-quality local hospital was identified for 3057 of 5000 patients (61.1%) in the testing cohort. Selecting the highest-performing hospital was associated with a 26.5% (95% CI, 24.5%-29.0%) relative reduction and 0.24% (95% CI, 0.23%-0.25%) absolute reduction in mortality risk. A mean amount of $1953 (95% CI, $1744-$2162) was gained in social welfare per patient treated. Simulated reassignment to a higher-quality local hospital was associated with a 23.5% (95% CI, 19.3%-32.9%) relative reduction and 0.26% (95% CI, 0.21%-0.30%) absolute reduction in mortality risk for Black patients, with $2427 (95% CI, $1697-$3158) gained in social welfare., Conclusions and Relevance: In this economic evaluation, using procedure-specific hospital performance as the primary factor in the selection of a local hospital for colorectal cancer surgery was associated with improved outcomes for both patients and society. Surgical outcomes data can be used to transform care and guide policy in colorectal cancer.

Objective: To evaluate microRNA expression in synovial fluid (SF), plasma, and leukocytes from patients with juvenile idiopathic arthritis (JIA)., Methods: MicroRNA expression in pooled JIA plasma and SF was assessed by absolute quantitative droplet digital PCR array. The results were validated in individual patient samples. MicroRNA content in leukocytes and extracellular vesicles was evaluated by real-time PCR in JIA blood and SF. Blood microRNA expression was compared with healthy controls (HCs). Principal component analysis was used to profile JIA plasma and SF microRNAs, and the potential biological consequences of microRNA dysregulation were investigated by pathway analysis., Results: MiR-15a-5p and miR-409-3p levels were higher in JIA plasma than in HC plasma. JIA SF contained elevated levels of miR-21-5p, miR-27a-3p, miR-146b-5p, miR-155-5p, and miR-423-5p, and decreased miR-192-5p and miR-451a, compared to JIA plasma. Extracellular vesicle analysis demonstrated variable encapsulation among selected microRNAs, with only miR-155-5p being represented substantially in extracellular vesicles. SF leukocytes also had higher expression of miR-21-5p, miR-27a-3p, miR-146b-5p, and miR-155-5p, and lower expression of miR-409-3p and miR-451a, relative to blood. No differences were observed between JIA and HC blood leukocytes. Clusters of microRNAs were commonly altered in JIA joint fluid and leukocytes compared to JIA blood samples. In silico analysis predicted that differentially expressed microRNAs in JIA target the transforming growth factor (TGF)-β pathway., Conclusion: The expression of multiple microRNAs is dysregulated in JIA both locally and systemically, which may inhibit the TGF-β pathway. These findings advance our knowledge of JIA immunopathogenesis and may lead to the development of targeted therapies., (Copyright © 2023 by the Journal of Rheumatology.)

Importance: A surgical consultation is a critical first step in the care of patients with emergency general surgery conditions. It is unknown if Black Medicare patients and White Medicare patients receive surgical consultations at similar rates when they are admitted from the emergency department., Objective: To determine whether Black Medicare patients have similar rates of surgical consultations when compared with White Medicare patients after being admitted from the emergency department with an emergency general surgery condition., Design, Setting, and Participants: This was a retrospective cohort study that took place at US hospitals with an emergency department and used a computational generalization of inverse propensity score weight to create patient populations with similar covariate distributions. Participants were Medicare patients age 65.5 years or older admitted from the emergency department for an emergency general surgery condition between July 1, 2015, and June 30, 2018. The analysis was performed during February 2022. Patients were classified into 1 of 5 emergency general surgery condition categories based on principal diagnosis codes: colorectal, general abdominal, hepatopancreatobiliary, intestinal obstruction, and upper gastrointestinal., Exposures: Black vs White race., Main Outcomes and Measures: Receipt of a surgical consultation after admission from the emergency department with an emergency general surgery condition., Results: A total of 1 686 940 patients were included in the study. Of those included, 214 788 patients were Black (12.7%) and 1 472 152 patients were White (87.3%). After standardizing for medical and diagnostic imaging covariates, Black patients had 14% lower odds of receiving a surgical consultation (odds ratio [OR], 0.86; 95% CI, 0.85-0.87) with a risk difference of -3.17 (95% CI, -3.41 to -2.92). After standardizing for socioeconomic covariates, Black patients remained at an 11% lower odds of receiving a surgical consultation compared with similar White patients (OR, 0.89; 95% CI, 0.88-0.90) with a risk difference of -2.49 (95% CI, -2.75 to -2.23). Additionally, when restricting the analysis to Black patients and White patients who were treated in the same hospitals, Black patients had 8% lower odds of receiving a surgical consultation when compared with White patients (OR, 0.92; 95% CI, 0.90-0.93) with a risk difference of -1.82 (95% CI, -2.18 to -1.46)., Conclusions and Relevance: In this study, Black Medicare patients had lower odds of receiving a surgical consultation after being admitted from the emergency department with an emergency general surgery condition when compared with similar White Medicare patients. These disparities in consultation rates cannot be fully attributed to medical comorbidities, insurance status, socioeconomic factors, or individual hospital-level effects.

Background: Little is known about the impact of multimorbidity on long-term outcomes for older emergency general surgery patients., Study Design: Medicare beneficiaries, age 65 and older, who underwent operative management of an emergency general surgery condition were identified using Centers for Medicare & Medicaid claims data. Patients were classified as multimorbid based on the presence of a Qualifying Comorbidity Set (a specific combination of comorbid conditions known to be associated with increased risk of in-hospital mortality in the general surgery setting) and compared with those without multimorbidity. Risk-adjusted outcomes through 180 days after discharge from index hospitalization were calculated using linear and logistic regressions., Results: Of 174,891 included patients, 45.5% were identified as multimorbid. Multimorbid patients had higher rates of mortality during index hospitalization (5.9% vs 0.7%, odds ratio [OR] 3.05, p &lt; 0.001) and through 6 months (17.1% vs 3.4%, OR 2.33, p &lt; 0.001) after discharge. Multimorbid patients experienced higher rates of readmission at 1 month (22.9% vs 11.4%, OR 1.48, p &lt; 0.001) and 6 months (38.2% vs 21.2%, OR 1.48, p &lt; 0.001) after discharge, lower rates of discharge to home (42.5% vs 74.2%, OR 0.52, p &lt; 0.001), higher rates of discharge to rehabilitation/nursing facility (28.3% vs 11.3%, OR 1.62, p &lt; 0.001), greater than double the use of home oxygen, walker, wheelchair, bedside commode, and hospital bed (p &lt; 0.001), longer length of index hospitalization (1.33 additional in-patient days, p &lt; 0.001), and higher costs through 6 months ($5,162 additional, p &lt; 0.001)., Conclusions: Older, multimorbid patients experience worse outcomes, including survival and independent function, after emergency general surgery than nonmultimorbid patients through 6 months after discharge from index hospitalization. This information is important for setting recovery expectations for high-risk patients to improve shared decision-making., (Copyright © 2022 by the American College of Surgeons.

As the surgical community continues to work towards greater diversity, equity, and inclusion, the need for buy-in from all surgeons-including those of the White majority-becomes increasingly apparent. This article invites all surgeons to aid in diversity, equity, and inclusion efforts as "allies," "upstanders," and "champions for change," and provides 2 specific frameworks for enacting allyship within the surgical field. Overt and conscious efforts to embrace allyship are imperative as we seek to fulfill our professional responsibilities to patients and will help create a workplace environment where all persons feel accepted, valued, welcomed, and respected., (Copyright © 2022 by the American College of Surgeons.

Background: Little is known about the impact of multimorbidity on outcomes for older emergency general surgery patients., Objective: The aim was to understand whether having multiple comorbidities confers the same amount of risk as specific combinations of comorbidities (multimorbidity) for a patient undergoing emergency general surgery., Research Design: Retrospective observational study using state discharge data., Subjects: Medicare beneficiaries who underwent an operation for an emergency general surgery condition in New York, Florida, or Pennsylvania (2012-2013)., Measures: Patients were classified as multimorbid using Qualifying Comorbidity Sets (QCSs). Outcomes included in-hospital mortality, hospital length of stay and discharge status., Results: Of 312,160 patients, a large minority (37.4%) were multimorbid. Non-QCS patients did not have a specific combination of comorbidities to satisfy a QCS, but 64.1% of these patients had 3+ comorbid conditions. Multimorbidity was associated with increased in-hospital mortality (10.5% vs. 3.9%, P <0.001), decreased rates of discharge to home (16.2% vs. 37.1%, P <0.001), and longer length of stay (10.4 d±13.5 vs. 6.7 d±9.3, P <0.001) when compared with non-QCS patients. Risks varied between individual QCSs., Conclusions: Multimorbidity, defined by satisfying a specific QCS, is strongly associated with poor outcomes for older patients requiring emergency general surgery in the United States. Variation in risk of in-hospital mortality, discharge status, and length of stay between individual QCSs suggests that multimorbidity does not carry the same prognostic weight as having multiple comorbidities-the specifics of which are important in setting expectations for individual, complex patients., Competing Interests: The authors declare no conflict of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: Disparate colorectal cancer outcomes persist in vulnerable populations. We aimed to examine the distribution of research across the colorectal cancer care continuum, and to determine disparities in the utilization of Surgery among Black patients., Methods: A systematic review and meta-analysis of colorectal cancer disparities studies was performed. The meta-analysis assessed three utilization measures in Surgery., Results: Of 1,199 publications, 60% focused on Prevention, Screening, or Diagnosis, 20% on Survivorship, 15% on Treatment, and 1% on End-of-Life Care. A total of 16 studies, including 1,110,674 patients, were applied to three meta-analyses regarding utilization of Surgery. Black patients were less likely to receive surgery, twice as likely to refuse surgery, and less likely to receive laparoscopic surgery, when compared to White patients., Conclusions: Since 2011, the majority of research focused on prevention, screening, or diagnosis. Given the observed treatment disparities among Black patients, future efforts to reduce colorectal cancer disparities should include interventions within Surgery., (Copyright © 2022.

Facial nerve trauma often leads to disfiguring facial muscle paralysis. Despite several promising advancements, facial nerve repair procedures often do not lead to complete functional recovery. Development of novel repair strategies requires testing in relevant preclinical models that replicate key clinical features. Several studies have reported that fusogens, such as polyethylene glycol (PEG), can improve functional recovery by enabling immediate reconnection of injured axons; however, these findings have yet to be demonstrated in a large animal model. We first describe a porcine model of facial nerve injury and repair, including the relevant anatomy, surgical approach, and naive nerve morphometry. Next, we report positive findings from a proof-of-concept experiment testing whether a neurorrhaphy performed in conjunction with a PEG solution maintained electrophysiological nerve conduction at an acute time point in a large animal model. The buccal branch of the facial nerve was transected and then immediately repaired by direct anastomosis and PEG application. Immediate electrical conduction was recorded in the PEG-fused nerves ( n = 9/9), whereas no signal was obtained in a control cohort lacking calcium chelating agent in one step ( n = 0/3) and in the no PEG control group ( n = 0/5). Nerve histology revealed putative-fused axons across the repair site, whereas no positive signal was observed in the controls. Rapid electrophysiological recovery following nerve fusion in a highly translatable porcine model of nerve injury supports previous studies suggesting neurorrhaphy supplemented with PEG may be a promising strategy for severe nerve injury. While acute PEG-mediated axon conduction is promising, additional work is necessary to determine if physical axon fusion occurs and the longer-term fate of distal axon segments as related to functional recovery., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Petrov, Burrell, Browne, Laimo, Roberts, Ali and Cullen.)

Introduction: Colorectal cancer is the second leading cause of cancer deaths in the USA, and screening tests are underutilized. The aim of this study was to determine the proportion of individuals at average risk who utilized a recommended initial screening test in a universal healthcare coverage system., Materials and Methods: This is a retrospective cohort study of active duty and retired military members as well as civilian beneficiaries of the Military Health System. Individuals born from 1960 to 1962 and eligible for full benefits on their 50th birthday were evaluated. Military rank or rank of benefits sponsor was used to determine socioeconomic status. Adherence to the U.S. Preventive Services Task Force guidelines for initial colorectal cancer screening was determined using "Current Procedural Terminology" and "Healthcare Common Procedure Coding System" codes for colonoscopy, sigmoidoscopy, fecal occult blood test, and fecal immunohistochemistry test. Average risk individuals who obtained early screening ages 47 to 49 were also identified., Results: This study identified 275,665 individuals at average risk. Of these, 105,957 (38.4%) adhered to screening guidelines. An additional 19,806 (7.2%) individuals were screened early. Colonoscopy (82.7%) was the most common screening procedure. Highest odds of screening were associated with being active duty military (odds ratio [OR] 3.63, 95% confidence interval [CI] 3.43 to 3.85), having highest socioeconomic status (OR 2.37, 95% CI 2.31 to 2.44), and having managed care insurance (OR 4.36, 95% CI 4.28 to 4.44)., Conclusions: Universal healthcare coverage does not ensure initial colorectal cancer screening utilization consistent with guidelines no does it eliminate disparities., (Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2021.
